What is fission fusion polygyny?
In ethology, a fission–fusion society is one in which the size and composition of the social group change as time passes and animals move throughout the environment; animals merge into a group (fusion)—e.g. sleeping in one place—or split (fission)—e.g. foraging in small groups during the day.
What is fission fusion in chimpanzees?
“Fission-Fusion” is a fancy title for how chimpanzee troops function in the wild. Troops can range from 25-100 chimps, and throughout the course of the day they will split up (fission) and come back together (fusion).
Do bonobos have a fission fusion society?
Atomistic communities, which are typical of chimpanzees, bonobos, dolphins, and spider monkeys, were also called “fission-fusion societies.” Molecular communities are typical of elephants, geladas, hamadryas baboons, and snub-nosed monkeys and are also called “multilevel societies,” in which different grouping levels …
How do primates choose mates?
The way monkeys select their mates all comes down to a group of genes called the major histocompatibility complex (MHC). According to the scientists, by choosing a partner who is MHC dissimilar, animals can increase their chances of their offspring being better able to resist disease.
Are baboons monogamous?

Where do chimpanzees sleep?
Chimpanzees know how to make a bed. Every night they climb up trees and curl up in nests they build out of branches and leaves. They sleep in the treetops to avoid nighttime predators such as leopards.
Why do female bonobos GG rub?
A genital-genital rub, better known as GG-rubbing by observers, is the most frequent behavior used by bonobo females to reinforce social ties or relieve tension. The other female mounts her and they rub their swellings right and left for several seconds, massaging their clitorises against each other.
How do primates mate?
An alpha male sits at the top, females are at the bottom, and all other males rank linearly in between. When a female is in heat, the skin around her genitals becomes pink and swollen — a clear sexual signal to males. Both male and female chimps elicit sex, though in a more brazen way than most people.
How do baboons find a mate?
Baboons can mate all year round, though females are only sexually active during their cyclical estrus, which typically lasts for 30 to 40 days. During a portion of this time, her rear end pads, that she normally uses for sitting, will become bright and swollen in order to attract males.
